Because you can never have too many ways to see the same thing. This is a browser based version of my satellite visualization from ealier today. Showing the February 10th coming together of US and Russian communication satellites, Iridium 33 and Cosmos 2251 over Siberia
Same idea as before, plots the locations of the two objects in the minutes leading up to the collision, but this one runs inside the Google Earth Plugin.
Use the time slider at the top of the screen to play the file back. The animation tracks the objects during the 6 minutes leading up to impact. Also included are the orbital paths (ground tracks) of the two objects between 16:00 and 17:00 GMT on February 10th.
Location data is based on the orbital elements for the two satellites, from Celestrak.
Here’s a browser based version of the (Feb 2009) UK Snowstorm Twitter activity, animated inside the Google Earth Plugin.
This mashes up 3800 Tweets over the course of a week. Users posting their location and the amount of snowfall they were seeing on a scale of 0 to 10. You can see how Twittersphere activity peaks on Monday February 2nd, the day the country ground to a halt. With sporadic outbursts every day over the following week.
Polygons are now directly clickable. Previously you had to click on them in combination with a key press to make their description bubbles appear.
Stylemap highlight styles are triggered by mouseovers on polygons and lines instead of just placemark icons.
The polygons in this file are drawn from Valery‘s KML Timezone map, posted on the Keyhole BBS a few years ago.
A much more significant event than the release of Google Earth 5.0 yesterday was the fact the much of Britain (particularly S. England) was covered by a sprinkling of snow. 😉
As a knock-on of this there’s been a large amount of media buzz about the use of Twitter as a mob-sourced geo-mashup generator to show snowfall.
Twitter users have been posting the first half of their postcode, plus the amount of snow in their location. 0 = no snow, 10 = bucket loads. ie: “#uksnow W12 9/10”
Developers have been mashing-up that data. Check out Ben Marsh’s neat, live Google Map mashup of this: #uksnow Tweets
#uksnow Twitter Animation, Google Earth 5
Now that the flurry (sorry) of activity has died down, I’ve trawled the Twitter API for the past few days of #uksnow hash tags (2200 so far) and put them into a KML time animation tailored to run in Google Earth 5:
